Recently,
debris flows caused by volcanic eruptions or landslide dams induced by
a heavy rainfall or an earthquake result in a great deal of serious
damage to many people.

Furthermore, under the growing impacts of
volcanic and seismic activities or global warming, relating large scale
sediment disasters, such as debris flows, is a matter of concern. In
order to manage the risk of the extraordinary debris flows, it is
necessary to revise the existing tools to predict a scale, place and
time of debris flow occurrence because of its extraordinariness.
Volcano and Debris Flow Research team aims at developing tools to
predict scale, place and time of the extraordinary debris flows and new
techniques for emergency surveys.
